Which disease is described by patches with granulation appearance, raised red-purple nodules, and nodular lesions with nodal and visceral involvement?

• A. Angiosarcoma
• B. Lymphoma
• C. Melanoma
• D. Kaposi's sarcoma

Answer: (D)

The pattern described—patches with a granulation-like, reddish-purple appearance that progress to raised nodules, plus involvement of nodes and internal organs in a disseminated form—is characteristic of Kaposi sarcoma. This vascular tumor, linked to HHV-8 and seen especially in immunocompromised individuals (like those with AIDS), often starts as flat patches on the skin, evolves into plaques, and can form nodules. If it spreads, it can involve regional lymph nodes and visceral organs, matching the described nodal and visceral involvement. The other options don’t fit this distinct multistage vascular skin lesion pattern: angiosarcoma is vascular but its presentation and progression differ; lymphoma centers on lymphoid tissue with nodal disease; melanoma is typically pigmented and not described by this vascular patch-to-nodule skin pattern.
